I To all whom it may concern:

Be it known that I, EDWIN G. Nmss- WANER, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have in- Vented certain new and useful Improvements in Reels for Motion-Picture Films, of which the following is a specification.

This invention is for a reel for receiving and holding motion picture films.

The invention has for its principal objects to provide a reel of rigid construction designed to withstand the hard usage to which devices of this kind are subject, and having improved film engaging means thereon, by virtue of which the attachment of the end of the film to the hub of the reel may be quickly and easily effected, said film engagin means preferably being of a material WhlCh will avoid, to the greatest possible extent, injury to the end of the film so attached.

These and other objects are attained by my invention, which may be readily understood by reference to the accompanying drawings,

Fig. 1 is a side elevation of a reel constructed in accordance with my invention;

Fig. 2-is a transverse section therethrough, in the plane of line IIII of Fig. 1;

Fig. 3 is an end view of the hub, showing the manner in which it is constructed;

Fig. 4 is a front elevation thereof;

Fig. 5 represents a cross section, on a larger scale, through the hub; and

Fig. 6 is a plan view of one of the film engaging members detached from the hub.

In' the drawings, 5 designates each of the two side plates which are formed of sheet metal and are of the necessary shape. The periphery of each disk is preferably curled outwardly to form a bead 6, to avoid the formation of sharp edges at a point where the film might be damaged by contact therewith.

The usual openings 7 are punched in the disks, leaving radial webs 8, portions of which may be pressed outwardly in any suitable fashion, as shown in the drawing, to provide strengthening webs.

The two disks are held in spaced relation to each other by a hub 9, which is preferably formed by bending into cylindrical form a strip of sheet metal which has previously heen stamped to shape. At each end of the huh are relatively long wide integral extensions 10, and at other points on the ends of the hub are short ears or projections 11,

fitted snugly a ainst the inner faces of the disks, and ben over the ed e of the metal disks through the openin s the bent-over portions being designate 10. The inner faces of the disks are preferably pressed outwardly, as indicated at 13, so that the faces of extensions will be set back out of the space between the disks, as clearly shown in Fig. 2. Notches are preferably cut in' the edge of the metal where part 10 is bent over, so that the bent ortion of the metal willbe flush with the e ge over which it is turned. The extensions might be spot welded to the disks in order to make the structure more secure.

The relatively wide long extensions 10 serve to provide a relatively large area of contact between the flanges and the disks, whereby the strength of the reel is materially increased over the common type where only ears, similar to ears 11, are provided. At the same time, the cost of manufacture is not greatly increased. The extensions 10 also serve to relieve ears 11 from much of the strain put upon them.

In the hub are one or more transversel extending slots 15, whose length is the width of the film which is wound upon the reel, so as to enable the end of a film to be inserted in the slots. I have shown two such slots, but there may be any desired number.

For securing the end of a film to the reel, I provide a rubber strip 16 having transverse hook-like lugs 17 on opposite ends thereof. This strip is stretched around a part of the hub and the lugs at the end thereof inserted ing t rough them, or, in other words, extend in a-plane whichis substantially tan ential to the circle defined by the hu at is, they roject into the slots transversely of the lengt :of the slots.

When the end of a film'is passed throu h" oneof the slots 15, the teeth 18 engage t e erforations in the film strip, and thereby old the end of the filmso' that it may be reeled up. Thus, it will be seen that the film may be very easily attached to the hub. The teeth bein of rubber are not likely to injure the film. the event of one of the rubber strips 16 becoming defective, it is a simple matter toreplace it with a new one, no oement being necessary to hold these strips in lace.

p Centrall positioned in the hub and supported in e disks 5, is a'central bushin of a type common in the art, through Whl a su porting shaft and key are passed.

arious changes and modifications may be made in the construction of the reel within the contemplation of my invention, and under the scope of the appended claims.

What I claim is:

1. A reel for motion picture films comprising a hub and side plates, said hub havmg a co-axially extending slot therein adapted to receive a film, and a tooth at each edge of the slot projecting part way across it for engaging a perforation in a film, the tooth at one side of the slot being adapted to engage the film when the reel is revolved in one direction and the tooth at the other side of the slot being'adapted to engage the film when the reel is revolved in the opposite direction.

2. A reel for motion picture films comprising a hub and side plates, said hub having a co-axial slot therein adapted to receive a film, and a tooth on the hub at each edge of the slot projecting transversely beyond the edge of the slot and adapted to engage in a perforation in the film when the end of a film is received in the slot, the tooth at one side of the slot being ada ted to engage the film when the reel is revo ved in one direction and the tooth at the other side of the slot being adapted to engage the film when the reel is revolved in the opposite direction.

3. A reel for motion picture films including a hub and side flanges, said hub having a slot therein, and means carried on the outside of the hub having a tooth thereon proieecting part way across the slot, said tooth ing positioned to engage a perforation in a film when the end of a film is positioned in f the slot.

4. A reel for motion picture films including a hub and side flanges, said hub having a slot therein adapted to receive the end of a vihen the end of the film is inserted in the s ot.

5. A reel for motidn picture films including a hub and side flanges, said hub hava slot therein ada ted to receive the en of a film, and a rub er strip removably carried 'by the hub on the outside thereof having a tooth extending part way across the slot and adapted for engagement with a perforation in a film when the end of the film is inserted in the slot.

6. A reel for motion picture films including a hub and side flanges, said hub having a slot therein adapted to receive the end of a film, a non-metallic strip secured to the outside of the hub, and a pair of teeth on the end of the strip adapted to project over the slot, the teeth being so spaced as to en perforations in the opposite sides of a strip when the end of the film is inserted in the slot.

7.
